Igneous rocks form in three main places: where lithospheric plates pull apart at mid-ocean ridges, where plates come together at seduction zones and where continental crust is pushed together, making it thicker and allowing it to heat to melting. There are two ideas about igneous rocks that are geologically important. The first idea is that igneous rocks evolve - they change from one kind of rock into another. The second idea is that rocks are not randomly distributed across the earth. Specific kinds

multiple pieces and is constantly moving, sliding past each other, and bumping into each other. These pieces are called tectonic plates and the edges of these plates are called the plate boundaries. Most earthquakes occur on these faults. The edges of the tectonic plates are rough and they become stuck on the one another while the rest of the plate keeps moving. When the tectonic plate moves far enough the edges unstick and the stored energy is released. The energy radiates outward from the fault in

WEAKNESSES OF THE BIG BANG THEORY According to Marmet (2005) , the big bang theory believes that the universe originated from an extremely dense concentration of material. The original expansion of this material is called the big bang theory. Moskowits (2010) describes the big bang theory as an assertion that the universe began extremely hot and dense. Around 14 billion years ago, space itself expanded and cooled down eventually allowing atoms to form and clump together to build the stars and galaxies

1. (6 points) Discuss Wegener’s evidence discussed in class regarding continental drift. Mention and briefly describe in detail three lines of evidence upon which he based his conclusion that continents had changed their latitude and longitude positions over time. Alfred Wegener figured out that the continents were one big land mass long before many others started to look into this. At first no one wanted to believe him, but later, after his death, other scientists started to agree with him. Wegener

Geologic features. The martian geology is different than Earth in many ways when it comes to the soil and the plate tectonics. Red soil. Mars is called the red planet for a reason. The soil on Mars is rich in magnetic iron oxides which is rust. Scientists took a soil sample that mimics that of Mars and tested it to see if it would rust the way it looks like on Mars. The iron was unchanged after a year in a dry atmosphere and finally changed when the sample was put in a wet atmosphere. (R., 2005)

1. Explain the relationship between continental drift and the formation of the Earth’s Oceans? The relationship between continental drift and the formation of Earth’s Oceans comes from the plate movement that occurred in Earth which is called plate tectonics. All of the landmasses were grouped together into one vast supercontinent called Pangea. Over millions of years the land started to split into many different countries and it also divided Panthalassa, the single great ocean that surrounded the

not like to live in one of the red areas on the map, because the red areas are where the strongest earthquakes occur. There will continue to be more and more earthquakes in those areas because they are on top of the tectonic plates and some lie within fault lines. A tectonic plate is a large irregular shape slab of solid rock. A fault line is a line of intersection between the fault plane and the Earth's surface. If I

hope to shed some light on the theory of continental drift and explain the various ideologies that attempt to explain these theories. The first term that must be understood in order to grasp the theory of continental drift is plate tectonics. The idea of plate tectonics dates back to the 1600’s, but was not given much credibility until 1915. It was at this time that meteorologist Alfred Wegner released a book based on his study of the continents. He proposed that the continents of the earth were

18, 1906, in San Francisco. This earthquake killed more than 3,000 people. Earthquakes happen when tectonic plates below the Earth collide, causing the Earth to move or split apart. Earthquakes are one of the most destructive/deadliest natural disasters in the world. Earthquakes occur when two blocks (tectonic plates) below the earth slide past each other causing friction. The surface where the plates slide past each other is called a fault line. The place below the earth’s surface where the earthquake
